This appears to be either an S351-29 or S390-29. The only difference between these two balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement, so compare both with your old hardware to see what matches best. In either case, choose a new stamp option of 2820. For the Top Sash Guide, start by looking at our 18-166. Review the dimensions and let me know if it matches your old guide. |
